中文摘要:
      介绍一种高性能吸水膨胀橡胶的制备新方法：在丙烯酸钠接枝天然胶乳制备吸水膨胀橡胶过程中，加入纳米晶纤维素（NCC）和纳米硅溶胶（NSS）以同时提高吸水膨胀橡胶的吸水性能和物理性能。结果表明，当丙烯酸钠单体用量为60份、NCC用量为0.75份、NSS用量为3份时，吸水膨胀橡胶的综合性能最好，吸水率达10.013，吸水平衡时间为11 h，二次吸水比率为97.3%，拉伸强度为12.25 MPa。
英文摘要:
      A new approach to prepare high performance water-swelling rubber was introduced.The water absorption property and physical properties of water-swelling rubber were improved by adding nano-crystalline cellulose（NCC） and nano-silica sol（NSS） in the preparation of water-swelling rubber with sodium acrylate grafted natural rubber latex.The results showed that the comprehensive properties of water-swelling rubber were better when 60 phr sodium acrylate，0.75 phr NCC and 3 phr NSS were used，and the degree of swelling was 10.013，equilibrium swelling time was 11 h，water absorption ratio for the second time reached 97.3%，and tensile strength was 12.25 MPa.
